> There should be an anti-downvoting/flagging facility

Like upvoting and vouching?

To be honest, I don’t think that comments are the problem. The community mostly does a good job of policing itself, especially once a thread gets enough visibility*. The problem is all the threads that get killed before they reach the front page (this post is a case in point).

* Although I will admit there are glaring blindspots you could drive a Panamax tanker through (especially political ones on the boundary between ideologies).
